Calculate The pH of a tomato is approximately $4.50 .$ What are $\left[\mathrm{H}^{+}\right]$ and $\left[\mathrm{OH}^{-}\right]$ in a tomato?
Identifying whether a solution is acidic, basic or neutral just from its ph is relatively easy. If you know these three guidelines, if the ph is equal to seven or some text books would say close to seven, I believe this one says equal seven, then the solution is neutral. If the ph is less than seven, it's acidic. If the ph is greater than seven, it's basic. So for lime juice, we have a ph of 2.2, it's less than seven. So it's acidic. A potato with a ph of 5.8 because it's less than seven, it's acidic. And then pure water with a ph of seven would be neutral and the last one bleach with a ph of 10, definitely greater than I'm a ph of 12, definitely greater than seven. This would be basic.
This is Chapter 18. Question 40. So we're looking for the each plus concentration and which one is concentration of a solution that has a pH of 4.50 In order to find this, we start off with the equation that the H plus concentration is equal to tend to the negative pH between that's equal to 10 to the negative 4.50 which is equal to 3.2 times 10 to the negative. Fifth. You have two significant figures here because our two decimal places in the log you then find the highest concentration by using the equation Kw sequel. Toothy concentration off protons, times the concentration of hydroxide and rearrange that equation. So you get the concentration of hydroxide is equal to K W over the age plus concentration plug in your values. So one times 10 to the negative, 14th over the 3.2 times 10 to the negative fifth and you get 3.2 times 10 to the negative 10th
How can we define fertilizers? Yeah, fertilizers can be defined as that they restore needed mineral nutrients to the soil.
Hello, everyone. Today I will be helping you with the second problem of the Chapter 25 problem set. So the question is asking what is humorous. And I would attack this problem by trying to define the key word, which is you, miss. So you may be wondering what is human. So this is a definition type of problem. So in order to get this right, you have to know what this is. So in simple terms, what he misses is it's the organic component of soil formed by the decomposition of leaves and other plant material by soil microorganisms. So basically what's happening is a lot of it will be. All of it is organic, and what it does is it supplies nutrients to the plants and the acidity of the decomposition releases minerals from the rock. So once you know what this is, I would go and I would attack this problem by process of elimination. So if we look at the first answer supplies, nutrients still plant that is true. So always put dots by the questions or by the answers that seem possible, B says is basic in its pH. So from one of the from one of the parts of humus is it's acidic. So, um, it's not basic in its pH. Otherwise, it's contrary to what the definition is, so we can cross that one off. Ah, si is found in the deepest soil horizons. Uh, no. It's the organic Claire. It's above the rocky layer. So we can cross that one out is inorganic and origin know the definition in states that it is organic due to the decomposition of leaves and other, um, things that may fall on the soil. So that leaves us with a So the answer is, is it supplies nutrients to the plants. I hope you found this video very helpful. Thank you very much.
